We need a stable and secure electricity supply in order for society to function. These outages, even those that last only for a short time, can have enormous consequences for public health and safety.

And as heat advisories and hurricane warnings mount, so do concerns about the power grid. In an era of extreme weather brought about by climate change, we can and should expect hotter summers and more intense tropical storms.
